Generate random maps from premade rooms in Unity

Created using Unity 2018.1

About

Create randomly generated dungeons from premade rooms by using only 3 components.

How to install

Copy the Assets/Scripts folder to somewhere inside your projects Assets folder. You may rename the folder to whatever you'd like. The prefabs and scenes folder are optional

How to use

Create a game object and add a MapGenerator component to it. Fill out the fields to your needs.

Next you need to create the rooms this generator can use. Create a game object that will be used as the room. Add a Room component and set the Bounds value which is used for the collision testing when trying to place a room. When editing the Bounds you should be able to see a Red rectangle based off it's values in the Scene View. Make sure the Bounds covers the whole room area.

Next your room needs X children with a RoomSpawn component. Move these children around to where the next room should spawn. The spawning works by aligning/connection the RoomSpawn spawns.

Once you have all your rooms created add them to the MapGenerator component. If you want a room to have a higher chance to appear you can add it multiple times.

To start the generation you just need to call the Generate() or Generate(int seed) function from the MapGenerator component.

Additional info

I was too lazy to add in the hallways, to do this they should be separate meshes from the room and a child of the room (1 hallway per spawn point). Then just create a component that checks if it's related spawn point is connected to a room if it isn't hide it.
